Therefore, different speed limit values are set for the vehicles in the speed limit station and outside the speed limit station, so that the vehicles are kept in a safe speed range, and accidents are avoided.

After the main inventive concepts of the embodiments of the present application are introduced, an application scenario diagram of a vehicle speed limit processing method provided by the embodiments of the present application is described below with reference to the accompanying drawings. The drawing comprises the following steps: a vehicle 101, a Road Side Unit (RSU) 102, and a speed limit station 103, wherein:

the vehicle 101 includes an On Board Unit (OBU), an On board GPS (GPS), and an attitude sensor. The vehicle-mounted unit is used for receiving speed limit configuration information sent by the roadside device 102 of the speed limit station 103, determining that a vehicle enters the entrance identification area based on the position information and the entrance direction angle information of the entrance identification area, the current position information and the current driving direction angle information of the vehicle, and carrying out speed limit processing on the vehicle according to a speed limit value corresponding to the speed limit station; and determining that the vehicle enters the departure identification area based on the position information and the departure direction angle information of the departure identification area, the current position information and the current driving direction angle information of the vehicle, and removing the speed limit treatment of the vehicle according to the speed limit value corresponding to the speed limit station.

Certainly, the method provided in the embodiment of the present application is not limited to the application scenario shown in fig. 1, and may also be used in other possible application scenarios, and the embodiment of the present application is not limited. Functions that can be implemented by each device of the application scenario shown in fig. 1 will be described together in the subsequent method embodiment, and will not be described in detail herein.

To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide method steps as shown in the following embodiments or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In steps where no necessary causal relationship exists logically, the order of execution of these steps is not limited to the order of execution provided by the embodiments of the present application.

Referring to fig. 2, a schematic flow chart of a vehicle speed limit processing method provided in the embodiment of the present application is shown.

As shown in fig. 2, the method comprises the steps of:

step 201, receiving speed limit configuration information sent by roadside equipment of a speed limit station; the speed limit station is a closed road area comprising an entrance and an exit, and the speed limit configuration information is used for identifying the position information and the entrance direction angle information of an entrance identification area corresponding to the entrance and the position information and the exit direction angle information of an exit identification area corresponding to the exit.

The vehicle and the roadside device of the speed limit station communicate with each other through a V2X (vehicle to X) network, and the roadside device of the speed limit station broadcasts the speed limit configuration information to the OBU in the vehicle through the V2X network.

Step 202, if the vehicle is determined to enter the entrance identification area based on the position information and the entrance direction angle information of the entrance identification area, the current position information and the current driving direction angle information of the vehicle, the vehicle is subjected to speed limit processing according to the speed limit value corresponding to the speed limit station.

And step 203, if the vehicle is determined to enter the departure identification area based on the position information and the departure direction angle information of the departure identification area, the current position information and the current running direction angle information of the vehicle, the speed limit processing of the vehicle according to the speed limit value corresponding to the speed limit station is removed.

The current position information and the current driving direction angle information of the vehicle can be determined according to the following modes:

the vehicle acquires the current position information of the vehicle through a GPS; and acquiring the running yaw angle of the vehicle in real time through the attitude sensor, and taking the acquired running yaw angle of the vehicle as the current running direction angle information.

Referring to the vehicle speed limit processing method shown in fig. 2, the relationship between the vehicle and the speed limit station is divided into two types, namely, the vehicle enters the speed limit station and the vehicle leaves the speed limit station. The entrance and exit of the speed-limiting station can be one or two different. If the speed-limiting station with the entrance and exit as two ports is taken as an example, the vehicle speed-limiting processing method will be described in terms of entering the speed-limiting station and leaving the speed-limiting station respectively.

1. Vehicle entering speed-limiting station

In the embodiment of the application, the entrance identification area is configured for the speed-limiting station with the entrance, so that the vehicle can be determined to enter the speed-limiting station only by determining that the vehicle enters the entrance identification area, and the speed-limiting treatment can be carried out on the vehicle according to the speed-limiting value corresponding to the speed-limiting station. For example, the speed limit value of a vehicle running on a normal road is generally about 50KM/H (kilometer per hour), the speed limit value in a speed limit station is 20KM/H, and if the vehicle enters the speed limit station, the vehicle can be subjected to speed limit processing according to the speed limit value corresponding to the speed limit station, and the speed limit value of the vehicle is modified from 50KM/H to 20KM/H.

In a possible implementation manner, the entry identification area includes an entry identification start point, and the location information of the entry identification area is the location information of the entry identification start point, so that in the embodiment of the present application, the vehicle is determined to enter the entry identification area based on the location information and the entry direction angle information of the entry identification area, and the current location information and the current driving direction angle information of the vehicle, and the steps as shown in fig. 3 may be performed:

step 301, detecting whether the vehicle passes through the entrance recognition starting point according to the position information of the entrance recognition starting point and the current position information of the vehicle acquired in real time.

Step 302, after the vehicle is determined to pass through the entrance identification starting point, the current driving direction angle information of the vehicle acquired in real time is compared with the entrance direction angle information.

Step 303, if the angle difference between the current driving direction angle information and the entrance direction angle information of the vehicle is not greater than the preset entrance angle, determining that the vehicle enters the entrance identification area.

For example, the current position information of the vehicle is acquired in real time and then compared with the position information of the entry recognition starting point shown in fig. 4, so that whether the vehicle passes through the entry recognition starting point can be detected. After passing through the entry identification start point, the current driving direction angle information of the vehicle is compared with the entry direction angle information shown in fig. 4. Because the vehicles are driven manually and the uncertain factors are more, for the convenience of comparison, a preset distance and a preset entry angle can be preset, if the difference value between the current position information of the vehicles acquired in real time and the position information of the entry identification starting point is not greater than the preset distance, the vehicles are detected to pass through the entry identification starting point, and if the angle difference value between the current driving direction angle information of the vehicles and the entry direction angle information of the vehicles is not greater than the preset entry angle, the vehicles are determined to enter the entry identification area.

In the horizontal driving direction, the entering direction angle information may be configured to be 0 degree, and when turning, at least one position may be selected to configure the entering direction angle information. The preset distance and the preset entrance angle can be set according to an empirical value or according to an actual situation, and the embodiment of the application does not limit the setting.

In another possible embodiment, in order to more accurately determine that the vehicle enters the speed limit station, as shown in fig. 5, the entrance identification area may further include an entrance identification start point, at least one entrance identification intermediate point, and an entrance identification end point, and entrance direction angle information is configured for each point. At this time, the position information of the entry identification area is all position information from the entry identification starting point to the entry identification end point, and therefore, in the embodiment of the present application, the entry identification area is determined based on the position information and the entry direction angle information of the entry identification area, the current position information and the current driving direction angle information of the vehicle, the current position information of the vehicle, which is acquired in real time, can be continuously compared with the entry identification starting point, at least one entry identification intermediate point, and the entry identification end point, the current driving direction angle information of the vehicle at each point is compared with the entry direction angle information configured at each point, and if it is determined that the angle difference between the current driving direction angle information of the vehicle at each point and the configured entry direction angle information is not greater than the preset entry angle, the vehicle is determined to enter the entry identification area. Therefore, the accuracy of determining that the vehicle enters the entrance identification area and the speed limit station is higher through multiple comparisons.

In a possible implementation manner, in order to more accurately determine the position where the speed limiting processing is performed on the vehicle according to the speed limiting value corresponding to the speed limiting station, as shown in fig. 6, a speed limiting position and a preset speed limiting distance may also be set in the embodiment of the present application. The speed limit position can be in the entrance identification area, such as the speed limit position 1 shown in fig. 6, or can be outside the entrance identification area, such as the speed limit position 2 shown in fig. 6. And if the vehicle enters the entrance identification area and the distance difference between the current position information of the vehicle and the speed-limiting position is not greater than the preset speed-limiting distance, determining to carry out speed-limiting processing on the vehicle according to the speed-limiting value corresponding to the speed-limiting station. The distance difference between the current position information of the vehicle and the speed-limiting position only represents the distance difference between the current position information of the vehicle and the speed-limiting position when the vehicle drives to the speed-limiting position. The specific implementation steps are shown in fig. 7:

and step 701, receiving speed limit configuration information sent by roadside equipment of the speed limit station.

Step 702, detecting whether the vehicle passes through the entrance identification starting point according to the position information of the entrance identification starting point and the current position information of the vehicle acquired in real time.

And 703, comparing the current driving direction angle information of the vehicle acquired in real time with the entrance direction angle information after the vehicle passes through the entrance identification starting point.

In step 704, if the angle difference between the current driving direction angle information and the entrance direction angle information of the vehicle is not greater than the preset entrance angle, it is determined that the vehicle enters the entrance identification area.

Step 705, comparing the current position information of the vehicle acquired in real time with the speed limit position.

And step 706, if the distance difference between the current position information of the vehicle and the speed limit position is not greater than the preset speed limit distance, performing speed limit processing on the vehicle according to the speed limit value corresponding to the speed limit station.

The speed-limiting position and the preset speed-limiting distance can be set according to an empirical value or an actual situation, and the embodiment of the application does not limit the speed-limiting position and the preset speed-limiting distance. Therefore, the position and time for carrying out speed limiting processing on the vehicle according to the speed limiting value corresponding to the speed limiting station can be accurately determined.

In a possible implementation manner, if the vehicle-mounted GPS signal strength is less than the preset signal strength threshold, as shown in fig. 8, in this embodiment, in step 801, a distance between the current position information of the vehicle and the center position of the speed limit station may also be determined;

in step 802, if the distance between the current position information of the vehicle and the center position of the speed limit station is not greater than the preset first distance threshold, and the angle difference between the current driving direction angle information of the vehicle and the entrance direction angle information of the vehicle is not greater than the preset entrance angle, it is determined that the vehicle enters the entrance identification area.

For example, as shown in fig. 9, since the vehicle-mounted GPS signal strength is less than the preset signal strength threshold value, so that the acquired current location information of the vehicle is not already actual location information, at this time, it cannot be determined whether the vehicle has entered the entry identification area according to the entry identification starting point, so that the distance between the acquired current location information of the vehicle and the center location of the speed limit station is compared with the preset first distance threshold value, and as long as the distance between the acquired current location information of the vehicle and the center location of the speed limit station is not greater than the preset first distance threshold value, at this time, since the current driving direction angle information of the vehicle is acquired according to the attitude sensor, the current driving direction angle information of the vehicle is the same as the current driving direction angle information acquired when the vehicle-mounted GPS signal strength is greater than the preset signal strength threshold value, so that the vehicle is considered to be in the entry identification area as long as the angle difference between the current driving direction angle information of the vehicle and the entry direction angle information is not greater than the preset entry angle.

In a possible implementation manner, as shown in fig. 10, if a passenger getting-off station corresponding to the vehicle is located in a speed-limiting station, in this embodiment of the application, a door opening and closing event may be detected at the passenger getting-off station by the vehicle, and it is determined that speed-limiting processing is not performed after the vehicle enters the entry identification area, speed-limiting processing is performed on the vehicle according to a speed-limiting value corresponding to the speed-limiting station.

For example, taking a bus as an example, if a terminal station of the bus is in a speed-limiting station, a vehicle-mounted OBU of the bus detects that a door opening and closing event occurs at the terminal station, and the speed-limiting process is not performed on the bus after the bus enters an entry identification area for various reasons, for example, the signal intensity of a vehicle-mounted GPS is smaller than a preset signal intensity threshold, based on the door opening and closing operation at the terminal station, the speed-limiting process is immediately forced to be performed on the speed-limiting vehicle according to a speed-limiting value corresponding to the speed-limiting station.

In one possible implementation mode, after a vehicle enters a speed limit station and carries out speed limit processing on the vehicle according to a speed limit value corresponding to the speed limit station, the speed limit value of the speed limit station is used as the highest speed capable of driving in the speed limit station, once the driving speed of the vehicle exceeds the speed limit value of the speed limit station, the vehicle-mounted OBU immediately reminds a driver through sound and light alarm, and records and uploads vehicle information such as a license plate number, driving time, driving speed and the like to a vehicle management place so as to trace an overspeed event subsequently.

2. Speed-limiting station for vehicle leaving

In the embodiment of the application, the departure identification area is configured for the speed-limiting station with the departure opening, so that the vehicle can be determined to leave the speed-limiting station only by determining that the vehicle enters the departure identification area, and the speed-limiting treatment of the vehicle according to the speed-limiting value corresponding to the speed-limiting station can be removed. For example, when a vehicle runs on a normal road, the speed limit value is generally about 50KM/H (kilometer per hour), the speed limit value in the speed limit station is 20KM/H, and if the vehicle leaves the speed limit station, the speed limit processing of the vehicle according to the speed limit value corresponding to the speed limit station can be removed, and the speed limit value of the vehicle is modified from 20KM/H to 50KM/H.

In a possible implementation manner, the departure identification area includes a departure identification starting point, and the location information of the departure identification area is the location information of the departure identification starting point, so that in the embodiment of the present application, it is determined that the vehicle enters the departure identification area based on the location information and the departure direction angle information of the departure identification area, and the current location information and the current driving direction angle information of the vehicle, the steps shown in fig. 11 may be performed:

step 1101, detecting whether the vehicle passes through the departure identification starting point or not according to the position information of the departure identification starting point and the current position information of the vehicle acquired in real time.

Step 1102, after the vehicle is determined to pass through the departure identification starting point, comparing the current driving direction angle information of the vehicle acquired in real time with the entering direction angle information.

Step 1103, if the angle difference between the current driving direction angle information and the departure direction angle information of the vehicle is not greater than the preset departure angle, determining that the vehicle enters the departure identification area.

For example, the current position information of the vehicle is acquired in real time and then compared with the position information of the departure recognition starting point shown in fig. 12, so that whether the vehicle passes through the departure recognition starting point can be detected. After passing through the departure identification start point, the current driving direction angle information of the vehicle is compared with the departure direction angle information shown in fig. 12. In order to facilitate accurate comparison, a preset distance and a preset departure angle can be preset, if the difference value between the current position information of the vehicle acquired in real time and the position information of the departure identification starting point is not greater than the preset distance, the vehicle is detected to pass through the departure identification starting point, and if the angle difference value between the current driving direction angle information of the vehicle and the departure direction angle information of the vehicle is not greater than the preset departure angle, the vehicle is determined to enter the departure identification area.

In the horizontal driving direction, the departure direction angle information may be configured to be 0 degree, and when turning, at least one position may be selected to configure the departure direction angle information. The preset distance and the preset departure angle can be set according to an empirical value and can also be set according to actual conditions, and the embodiment of the application does not limit the distance and the departure angle.

In another possible embodiment, in order to determine that the vehicle leaves the speed limit station more accurately, as shown in fig. 13, the departure identification area may further include a departure identification start point, at least one departure identification intermediate point, and a departure identification end point, and departure direction angle information is configured for each point. The position information of the departure identification area at this time is all the position information from the departure identification start point to the departure identification end point.

Therefore, in the embodiment of the application, the vehicle entering the departure identification area is determined based on the position information and the departure direction angle information of the departure identification area, and the current position information and the current driving direction angle information of the vehicle, the current position information of the vehicle obtained in real time can be continuously compared with the departure identification starting point, at least one departure identification intermediate point and the departure identification terminal point, the current driving direction angle information of the vehicle at each point is compared with the departure direction angle information configured at each point, and if the angle difference between the current driving direction angle information of the vehicle at each point and the configured departure direction angle information is determined to be not greater than the preset departure angle, the vehicle is determined to enter the departure identification area and leave the departure speed limit station. Therefore, the accuracy of determining that the vehicle enters the departure identification area and leaves the speed limit station is higher through multiple comparisons.

In a possible implementation manner, in order to more accurately determine the position for releasing the speed limit processing of the vehicle according to the speed limit value corresponding to the speed limit station, as shown in fig. 14, a speed limit releasing position and a preset speed limit releasing distance may also be set in the embodiment of the present application. The speed limit releasing position is located in the departure identification area, for example, a speed limit releasing position 1 or a speed limit releasing position 2 shown in fig. 14.

And if the vehicle enters the departure identification area and the distance difference between the current position information of the vehicle and the speed limit releasing position is not more than the preset speed limit releasing distance, determining the position for releasing the speed limit processing of the vehicle according to the speed limit value corresponding to the speed limit station. At the moment, the distance difference between the current position information of the vehicle and the speed limit releasing position only represents the distance difference between the current position information of the vehicle and the speed limit releasing position when the vehicle drives to the speed limit releasing position. The specific implementation steps are shown in fig. 15:

step 1501, receiving speed limit configuration information sent by roadside equipment of the speed limit station.

Step 1502, detecting whether the vehicle passes through the departure identification starting point according to the position information of the departure identification starting point and the current position information of the vehicle acquired in real time.

And step 1503, comparing the current driving direction angle information of the vehicle acquired in real time with the departure direction angle information after the vehicle is determined to pass through the departure identification starting point.

Step 1504, if the angle difference value between the current driving direction angle information and the departure direction angle information of the vehicle is not larger than the preset departure angle, determining that the vehicle enters the departure identification area.

In step 1505, the current position information of the vehicle acquired in real time is compared with the speed limit releasing position.

And step 1506, if the distance difference between the current position information of the vehicle and the speed limit releasing position is not greater than the preset speed limit releasing distance, releasing the speed limit processing of the vehicle according to the speed limit value corresponding to the speed limit station.

The speed limit releasing position and the preset speed limit releasing distance can be set according to an empirical value or an actual situation, and the embodiment of the application does not limit the speed limit releasing position and the preset speed limit releasing distance. Therefore, the position and time of speed limiting processing of the vehicle according to the speed limiting value corresponding to the speed limiting station can be accurately determined and solved.

In a possible implementation manner, if the on-board GPS signal strength is less than the preset signal strength threshold, as shown in fig. 16, in this embodiment, in step 1601, the distance between the current position information of the vehicle and the center position of the speed-limiting station may also be determined;

in step 1602, if the distance between the current position information of the vehicle and the center position of the speed-limiting station is greater than a preset second distance threshold, and the angle difference between the current driving direction angle information of the vehicle and the departure direction angle information of the vehicle is not greater than a preset departure angle, it is determined that the vehicle enters the departure identification area.

For example, as shown in fig. 17, since the vehicle-mounted GPS signal strength is less than the preset signal strength threshold value, which results in that the acquired current location information of the vehicle is not already actual location information, in this embodiment of the application, the distance between the acquired current location information of the vehicle and the center position of the speed limit station may be compared with the preset second distance threshold value, and as long as the distance between the acquired current location information of the vehicle and the center position of the speed limit station is greater than the preset second distance threshold value, since the current driving direction angle information of the vehicle is acquired according to the attitude sensor, the current driving direction angle information of the vehicle is the same as the current driving direction angle information acquired when the vehicle-mounted GPS signal strength is greater than the preset signal strength threshold value, and therefore, as long as the angle difference between the current driving direction angle information of the vehicle and the departure direction angle information is not greater than the preset departure angle, the vehicle is considered to be in the departure identification area.

The preset second distance threshold may be set according to an empirical value, or may be set according to an actual situation, which is not limited in the embodiment of the present application.

In addition, the distance between the current position information of the vehicle and the position information of the departure identification starting point can be compared with a third distance threshold, and as long as the distance between the current position information of the vehicle and the position information of the departure identification starting point is far greater than the third distance threshold and the angle difference between the current driving direction angle information of the vehicle and the departure direction angle information of the vehicle is not greater than a preset departure angle, the vehicle is determined to leave the speed-limiting station, and the speed-limiting processing of the vehicle according to the speed-limiting value corresponding to the speed-limiting station is released. The third distance threshold may be set according to an empirical value, or may be set according to an actual situation, which is not limited in this embodiment of the application.

In a possible implementation manner, as shown in fig. 18, if the passenger boarding station corresponding to the vehicle is located outside the speed limit station, in this embodiment of the application, the speed limit processing performed on the vehicle according to the speed limit value corresponding to the speed limit station may also be removed when the vehicle detects that a door opening and closing event occurs at the passenger boarding station and determines that the speed limit processing is not removed after the vehicle enters the departure identification area.

For example, taking a bus as an example, if the starting station of the bus is outside the speed-limiting station, the vehicle-mounted OBU of the bus detects that a door opening and closing event occurs at the starting station, and the speed-limiting process is not performed on the bus after the bus enters the departure identification area for various reasons, for example, the signal intensity of the vehicle-mounted GPS is smaller than a preset signal intensity threshold value, the speed-limiting process performed on the bus according to the speed-limiting value corresponding to the speed-limiting station is immediately forcibly removed based on the door opening and closing operation at the starting station. In addition, the bus has non-operation conditions, such as refueling, gas filling, bus customization and the like, besides a normal operation line, and the bus does not stop no matter whether the starting station is in the speed-limiting station or outside the speed-limiting station. At this time, in addition to the fact that whether the vehicle enters the departure identification area or not can be judged by using the vehicle speed limit processing method provided by the embodiment of the application, the distance between the current position information of the vehicle and the position information of the departure identification starting point can be compared with the third distance threshold, and as long as the distance between the current position information of the vehicle and the position information of the departure identification starting point is far greater than the third distance threshold, the speed limit processing of the speed limit vehicle according to the speed limit value corresponding to the speed limit station is released.

Therefore, in the embodiment of the application, different speed limit values are set for the vehicles in the speed limit station and outside the speed limit station, the field identification area and the departure identification area are arranged outside the speed limit station, and the speed limit values of the vehicles are modified by determining that the vehicles enter the speed limit station or leave the station, so that the vehicles are kept in a safe speed range, and accidents are avoided.

Based on the foregoing description, the embodiment of the application receives speed limit configuration information sent by roadside equipment of a speed limit station; the speed-limiting station is a closed road area comprising an entrance and an exit, and the speed-limiting configuration information is used for identifying the position information and the entrance direction angle information of an entrance identification area corresponding to the entrance and the exit information of an exit identification area corresponding to the exit; if the vehicle is determined to enter the entrance identification area based on the position information and the entrance direction angle information of the entrance identification area, the current position information and the current driving direction angle information of the vehicle, carrying out speed limit processing on the vehicle according to the speed limit value corresponding to the speed limit station; and if the vehicle is determined to enter the departure identification area based on the position information and the departure direction angle information of the departure identification area, the current position information and the current driving direction angle information of the vehicle, the speed limit processing of the vehicle according to the speed limit value corresponding to the speed limit station is removed.
